battery won’t load

[Arno Trautmann]

Hi,

I have a X61s, now about 2 years old. Used it a lot, carried it around
nearly every second day. Never had any problems with the battery.

Now I get:

[arno@tiger]$ cat /proc/acpi/battery/BAT0/info
present:                 yes
design capacity:         74880 mWh      ⇐
last full capacity:      52420 mWh      ⇐
battery technology:      rechargeable
design voltage:          14400 mV
design capacity warning: 2621 mWh
design capacity low:     200 mWh
capacity granularity 1:  1 mWh
capacity granularity 2:  1 mWh
model number:            93P5030
serial number:            6195
battery type:            LION
OEM info:                SONY

Ok, maybe the battery is bad now and will hold only 52Wh. But actually,
it does not:

[arno@tiger]$ cat /proc/acpi/battery/BAT0/state
present:                 yes
capacity state:          ok
charging state:          charged
present rate:            0 mW
remaining capacity:      1800 mWh       ⇐
present voltage:         16195 mV

The machine is plugged in, but the remaining capacity stays at 1800 mWh.
This happened just a few days ago, since then the remaining capacity
changed from like 1650 mWh to 1800 mWh.

So my question: what can I do? Is the battery useless? Can I recover it
anyhow? Could this be a software issue or is it hardware?

cheers
Arno

Its a bit strange this problem at first look you battery is near of
death, and the voltage is hight you can perhaps check check the cable
and the device who work whith sorry i dont know how this name on english

There was a recall/replacement program for batteries on that
model. Unfortunately mine was denied for being more than one year out
of warranty.  Check the lenovo website.

It’s plugged in, so the voltage is not from the battery, but from the
power supply.

You got denied a replacement battery in a public-safety-related recall
because it was old and out-of-warranty?  Are you sure it was not because
your batterie's serial number indicated that it was not in one of the bad
manufacturing runs?

Or was this a different recall, not related to batteries catching fire and
blowing up?

Will it do anything if not plugged in?
Most TP battieries are three sets ( in series ) of a pair of cells stapped together.
If one cells shorts it blows an internal fuse in it's brother and the battery is completely
open.

Right. The batteries stopped working, but apparently no safety hazard.

The battery in my t61p has also starting acting up.  It does not
charge, and the machine has to run on AC power.

I'm not so sure about it, but with tp_smapi you can see the voltage of
each group of cells in the battery:
cat /sys/devices/platform/smapi/BAT0/group?_voltage
